I agree, I was convinced to shell out the cash for the first time in 2009 after always owning PCs (and a couple free Ataris & 1 free Mac in the 90s).It was definitely more expensive than comparable Win laptops. But I had a good job and low expenses. What got me was that it had a metal case, the multi touch track pad is awesome and it was a reasonably powerful computer. Also, I dj in nightclubs using Serato which happens to be more stable in OS X (it started on the Linux platform but I suppose they switched due to OS market share).
I currently dual boot it in Win7 (which I am using at the moment). I also got a small amount of RAM then installed my own after my warranty was up. If I had to gripe about anything at this point it's really mostly the price and sometimes I wanna mess with something that OS X just doesn't allow me to access, but the fact that it's based on BSD has remedied some of those issues.
